No, alas, because there would be all sorts of copyright problems, but some of the people attending will probably make recordings of some of the tunes played for their personal use as Will has invited them to do that.
I hope that some festivals will get Will to do some similar sessions - you could ask your local one to book him - and there's no doubt that we'll want him to do more workshops for us in future.
Thanks for taking an interest, and hope to see you in Lewes one of these days,
